Another strategy for graphing a piecewise function is to use a table of values. The table below has a column for the input value

s x and for each piece of the function. The shaded cells indicate where the pieces do not define the function for those input values and so you do not need to find those values. You will need to decide which piece is used to define the function when x=3

The number a is smaller than the number b by 1/5 of b. By what part of a is b bigger than a?
Ira Lisetskai [31]

Answer:

The number b is bigger than the number a by \dfrac{1}{4} of a.

Step-by-step explanation:

1. If the number a is smaller than the number b by 1/5 of b, then

a+\dfrac{1}{5}b=b.

Thus,

a=b-\dfrac{1}{5}b=\dfrac{4}{5}b,\\ \\b=\dfrac{5}{4}a.

2. Consider the expression b=\dfrac{5}{4}a:

b=\dfrac{5}{4}a=\dfrac{4}{4}a+\dfrac{1}{4}a=a+\dfrac{1}{4}a.

This gives you that the number b is bigger than the number a by \dfrac{1}{4} of a.

first i like to make them a decimal so its easier.

1/4 = 0.25

1/5 = 0.2

multiply 0.25 and 0.2 = 0.05

make 0.05 a fraction

1/20

simplify. (it's already in its simplest form)

the answer is 1/20 as a fraction or 0.05 as a decimal.
